Adding further speculation to the reasoning behind Apple's recent health and science-focused hiring spree, the prospective iWatch-maker is at it again, this time touting a new opening for an "exercise physiologist."

Since a professional of this nature wouldn't likely be assigned to an already existing Apple product, this job posting suggests that a new device within a new product category is in the planning stages for Apple.

Lending more credence to suspicions that Apple's rumored forthcoming iWatch will be very health and fitness-focused, today's job posting follows a string of recent reports indicating that iOS 8 will be the most health-centric mobile operating system refresh to date from Apple. All told, it's a strong indication that Apple is ready and willing to capitalize on the red-hot wearable tech market.

For those wondering what the candidate who is ultimately selected will actually do for Apple, the company describes the position as an opportunity to "design and run user studies related to cardiovascular fitness & energy expenditure, including calories burned, metabolic rate, aerobic fitness level measurement/tracking and other key physiological measurements."

To date, Apple is yet to formally announce or confirm plans for the so-called "iWatch."
